Welcome: U-THERM INTERNATIONAL (H.K.) LIMITED
Introduction:
· The most widely used pH + Conductivity Double-Parameter measurement meter.
· Meter meets with the requirement of international GLP standards. Its features up to automatic calibration, automatic temperature compensation, data storage, timing measurement, clock display, RS-232 output, function setting and self-diagnose etc.
· There are three different measurement modes: stable display mode; time measurement mode; continuous measurement mode.
· Automatically recognize pH buffer solution. User can choose anyone from three series of standard buffer solutions: Europe & USA series, NIST series and China series.
· Adopt advanced and original conductivity measurement technology, use 1 pc of conductivity electrode (K=1), it can meet measuring accuracy requirement for range within 0.5μS/cm ~ 200mS/cm by using only one-point calibration.
· Can switch Conductivity, TDS, Salinity and Resistivity.
· Meter has the only product serial number.
· Dustproof and waterproof meter meets IP54 standards. All sockets are seal protected by the silica gel caps.
